Now let's see how to make 1 N and 1M H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl / density 98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula 1M H2SO4 (98%) = 53.30 ml [ V ] 100% ...
After alpha , beta, gamma , and delta plus variant of covid-19 the new variant of covid-19 omicron has came in market and has already started to spread all over the world. Origin of omicron : According to recent information County Botswana of the South Africa was place place where first case of omicron found. But it's not true actually south Africa was the one who informed all world about new variant omicron. That was south africa goodness. After all this time, now know we know where omicron really came from. Now Netherland, Belgium and Germany revealed that omicron was already present in our country's before south Africa. According to Netherlands on November 19th they took some samples from Corona affected people and that's when they realized there is new variant of covid-19 and now they have announced lockdown in Netherland. In Netherland theaters, Bar, restaurants, will be close after 5 o.clock . That's me...
